Alexander Graham Bell worked on devices that would help kids and adults who had severe hearing loss. One of his devices was a single headphone that could effectively deliver loud sound to a deaf person. He used a microphone that he invented, so that people could talk to the headphones that the deaf were listening to.
The device worked wonderfully, and Bell went on to invent a device that combined the headphone in the same container as the microphone. He referred to his new device as a "telephone".
Bell's last name was later used as a new unit for measuring the strength or loudness of sounds, and it was called the Bel. A Bel defines a pretty loud sound, way beyond what would be heard around the house or in town. Scientists back then thought it would work better for most things to use one/tenth (1/10) of a Bel, instead. In the metric system, it was called a deciBel. The "B" is capitalized because the unit, Bel, was taken from someone's name. The abbreviation for deciBel is dB, still using that capital "B".
The first person who made headphones was Nathaniel Baldwin.

Lawrence J. Fogel thought up the original concept that is used in noise canceling headphones but Dr. Amar Bose of the Bose Corporation actually made the first set of headphones to utilize the technology.

Headphones were first used by the military in the late 1920s

Headphones such as Dr. Dre beats and Bose headphones are ranked as one of the best headphones in the modern world. The sound quality is excellent and the prices is very reasonable.
You can buy very cheap headphones in a variety of places such as dollar stores, discount stores, flea markets, and even Wal-Mart. Beware though, the quality of the headphones may be sub par.
Dr.Dre headphones and Bose headphones are great for running and are the best for running with. They are very tight fitting and perfect for runners. They are lightweight too.
Sony headphones are very easy to clean because the material easy cleans.

The first truly successful headphones were made by Nathaniel Baldwin. Baldwin made the headphones by hand in his kitchen and later he sold them to the U.S navy. Sensitive headphones like those were soon being manufactured by Brandes in 1919 and were commonly used for early radio work. The headphones were made by moving iron drivers (either single ended or balanced armature). Old headphones like those had very poor comfort and the quality was crude. Today's headphones have come a long way since then and seem to keep improving.
